("back up" when used as a verb) A spare
copy of a file, file system, or other resource for use in the
event of failure or loss of the original.

The term commonly refers to a copy of the files on a
computer's {disks}, made periodically and kept on {magnetic
tape} or other removable medium (also called a "{dump}").

This essential precaution is neglected by most new computer
users until the first time they experience a {disk crash} or
accidentally delete the only copy of the file they have been
working on for the last six months. Ideally the backup copies
should be kept at a different site or in a fire safe since,
though your hardware may be insured against fire, the data on
it is almost certainly neither insured nor easily replaced.

See also {backup software}, {differential backup},
{incremental backup}, {full backup}. Compare {archive},
{source code management}.
